* method: add

* name - The name of the field to validate
* type - The type of the field, methodology to use when validating
* required - Boolean true or false, whether the field is mandatory or not
* options - Other validation restrictions
*
* notes:
* - An idea to expand on the flexibility here is to allow a field to be validated multiple times by different types
* would allow you to layer validations instead of forcing the construction of customised validators which just
* do two or three simple validation types together, this would require changing the structures a little bit because
* right now, the field name is used as the key to the type of validator, we'd have to change that so each key can have
* multiple types assigned to it
* - I think to allow an item to be validated multiple times, we could just move to a system where
* we don't use the $name parameter as the key to the rules array, we simply add a new rules[] element
* and then loop through them identically, we could move the $name parameter into the array assigned
* as the same "name" array index and it should work identically
* - I think we need to stop assigning validData items to a blank string by default, because if an item
* doesn't validate, it shouldn't appear in the array, but having a string here is beneficial because
* it means you can just print the element and it'll print a blank string if it failed to validate.
* this SOUNDS a good idea, until you start to think of situations where knowing it failed to validate
* by merely looking for it and seeing it's not present is actually useful too.
* The problem here seems to be a lack of direction, we haven't decided yet which is the best course of action
